摘要
基于抚顺市章党观测站1961—2010年的逐日平均气温、最低气温和最高气温资料,利用趋势分析和M-K突变分析对章党站的平均气温、最高气温和最低气温的气候变化特征等进行分析。结果表明:章党站年平均气温呈显著上升趋势,其气候倾向率为0.18℃/10 a;各季节的气温均呈上升趋势,其中冬季平均气温上升趋势最强,春季次之,夏季、秋季最弱;章党站的年平均气温在20世纪80年代后期发生突变,1997年后平均气温上升趋势显著。
In this paper,the characteristics of temperature in Zhangdang station of Fushun City were analyzed based on the daily mean temperature ,daily maximmn temperature and daily minimum temperature during 1961 to 2010 by using tendency analysis and Mann-Kendall method. The results showed that the temperature in Zhangdang in the latest 50 years showed the ascending trend,and the tendency rate of the mean temperature was 0.18 qC/10 a.The seasonal average temperature showed an upward trend, and the trend of winter was the strongest,and the trend of spring was the second ,the trend of summer and autumn were the weakest.The average temperature in Zhangdang station changed suddenly in the late 1 980 s ,and the mean temperature rised significantly in 1997.
